Abstract
We lhave investigated possible sources of uncertainties in antenna Iictors determined per ANSI C63.S. standard site method. Errors (:ai pnrticularly occur due to height-dependent antenna factors in the r'requericy ratige o f 30-200 MHz. Suggested improvements iiiclude I he use of i i n "antenna 2" having a height-independent antenna factor. selection of the assignment of "antenna 1 ". "2" and "3" to the iiiitenna under calibration directed to the specific application. tletei~tnination of antenn;i factors as functions of polarization and height above ground. and use of higher frequency resolution.
我们已经调查了根据ANSI C63.S确定的天线矢量中可能的不确定性来源。标准现场方法。在频率范围为30- 200mhz的情况下，高度相关的天线因素尤其会产生误差。建议的改进包括在具有与高度无关的天线因子的“天线2”中使用I I I。选择“天线1”的分配。“2”和“3”到被校准的天线，指向特定的应用。天线的偏振度。偏振度和离地高度的函数。并使用更高的频率分辨率。
